Let me start by saying I'm brimming with pride of my beloved Wife

!
We went to our local indoor-range yesterday (I spend A LOT of time there when I can....

) and I coached the Wife along as she went through several types of ammo (165 Grain FMJ, 180 Grain FMJ, 135 Grain JHP, 180 Grain JHP), with our home defense Gen 3 G23, and my carry Gen 3 G22.
This is 20 rounds, 180 Grain FMJ at 5 yards with a Gen 3 Glock 23:
BTW, the neck shot was her first round....she started keeping things in the 8 ring after that...count 'em up fellas, they're all there

!
Here she is rocking my carry gun, a Gen 3 Glock 22 fitted out with Tru-Glo TFO's

!
Yeah Baby!!! Arms out, thumbs forward, GREAT FORM!!!
And finally, here she is KILLING IT with the Glock 23, 3 Yds, 10 Rnds of 180 Grain JHP

!!!!
My Wife of 20+ years apparently has no problem handling .40.....
Truth be told, she's been shooting Glock 23's for about 19 years or so; she's been shooting this particular Glock 23 for roughly 7-8 years....
And to be perfectly honest, the Glock 23 is actually
hers, even though I borrowed it for a few years as my EDC gun....
It's all hers now, and we currently use it for home defense.
We, as a family, don't see anything wrong with the .40.....and my Wife is ready for when things go bump in the night, that I can tell you
